How to remove old Airplay Devices?

Good to hear it finally went away. But a "Remove" button would be nice. Thank you for your response.

Have you tried restarting your iPhone?

Normally you will see a list of available AirPlay devices if they are available. The devices cannot be deleted as they are removed themselves if they are not available. Make sure your TV is not connected to Wi-Fi, possibly also Bluetooth if the TV has it.

Then, do a Forced Restart of your iPhone.

1. Press and quickly release Volume Up

2. Press and quickly release Volume Down

3. Press and hold the Side Button, the phone will restart. Release when you see the Apple Logo

Okay, I'm out of ideas then. The last hope is that it disappears on its own. The info I can find is that AirPlay devices that have not been connected for 30 days disappear automatically. Alternatively, you have to start with the big Factory Reset solution, but I think it's a bit drastic. By the way, have you updated to iOS 16.4 - a simple update can also sometimes solve such small "glitches"

Ok you have done a Forced Restart Hmm mysterious. If the TV is not on Wi-Fi then you should not be able to see it.

Have you tried logging into your router's settings - this is done from the browser on your phone or computer, some routers also have an app that can be used. But inside those settings you can see the devices that have been signed in to Wi-Fi, and remove them as trusted devices. In this way, you are sure that the TV does not appear on the network. Alternatively, you can change the Wi-Fi code - this is more cumbersome, however, as you then have to set up all devices again.

You are welcome, unfortunately I did not have the answer. But I hope the device goes away after some time.
